Скачать или смотреть The Pumpkin Microphone Array

Here is our first prototype of an ambisonic microphone array with a non-spherical scattering body. (Sorry for the background noise. It's from the ventilation system in the room.)

The underlying method is described in this article:

Jens Ahrens, Hannes Helmholz, David L. Alon, Sebastià V. Amengual Garí, “Spherical Harmonic Decomposition of a Sound Field Using Microphones on a Circumferential Contour Around a Non-Spherical Baffle," ACM/IEEE Transactions on Audio, Speech, and Language Processing, 2022

Find a pdf of it here: https://research.chalmers.se/publicat...

We applied equalization in the spherical harmonic domain as described in the appendix of the article.
